Update the AASHTO Pavement Management Guide

Description:

The 2nd edition of the AASHTO Pavement Management Guide was published in 2012. Since its publication there have been many changes in pavement management practices. The 2021 update to the FHWA’s Pavement Management Roadmap identified significant interest in developing more step-by-step assistance on many topics to support the practitioners’ training demands. In addition to updating existing topics, potential additions to the new Pavement Management Guide might include: · Enhancing data collection activities o Contracting practices o Using traffic speed deflectometer data (TSD) to define network structural condition o Using ground penetrating radar o Establishing precision and bias statements o Improving data quality · Managing large data sets effectively o Strategies for archiving data o Using artificial intelligence, machine learning, and other tools to analyze data · Developing effective performance models o Evaluating the reasonableness and reliability of models o Updating models with new information such as structural data, risk, and resilience factors · Improving project and treatment selection o Incorporating new factors into the models, such as structural data, sustainability, equity, and resilience o Incorporating pre-treatment condition into treatment selection o Improving the match between planned and programmed projects · Using pavement management information to drive decisions o Setting targets o Developing asset management plans o Presenting analysis results effectively.

Numerous studies, both at the local, national, and international level, have been conducted related to the topics noted for update. For example, a comprehensive literature search and practice survey were conducted as part of the FHWA’s efforts to update the Pavement Management Roadmap. The results from these efforts are available through FHWA. In addition, TSD studies have been conducted for utilizing structural assessment in pavement management decisions. With the adoption of data quality management plans, state highway agencies and the FHWA (e.g., TPF-5(105)) have conducted studies for improving data quality. Efforts are on-going for defining and quantifying sustainability, equity, and resilience for use in pavement management.

Objective:

This research will address these demands through an update to the AASHTO Pavement Management Guide in an online, searchable document that can be revised as new research and technical materials become available. The research objectives will be accomplished through the following activities:

Identify new content to be addressed in the updated Pavement Management Guide.

Present an approach for modifying or replacing the 2012 Pavement Management Guide, including suggestions for whether a print version will be published.

Develop the material for the new Guide using available resources and case examples.

Identify other resources that could be incorporated into an online version of the document, such as videos, training materials, and so on.

Develop an online version of the updated AASHTO Pavement Management Guide with search features and hyperlinks to the Pavement Management Roadmap.

Conduct a book club to promote the completed Guide.

Benefits:

Updating the AASHTO Pavement Management Guide will provide agencies with a more complete document on today’s practices and procedures, updating current guidelines, while including others that have been in use since publication of the current version of the guide. Because of the importance of pavement management to support Asset Management and Transportation Performance Management efforts, this research has been flagged as critically important to practitioners in transportation agencies.

Implementation:

Within a typical State DOT, staff from pavement design, pavement management, asset management, and performance management will likely be responsible for using the research results. The following are some of the potential implementation activities required following this research effort, so that State DOTs can implement the research results within their own organization:

Independent validation and verification studies by reputable research and development entities with sound engineering and statistical principles to demonstrate applicability of the technology to practical use cases for State DOT and Local agencies.

FHWA Center for Accelerating Innovation (CAI) programs can be used to provide funding to State and local agencies who would like to conduct pilot projects with the proposed technology.

Establish feasibility and usability in practice for these technologies to be implemented in a phased approach in various maintenance and asset management applications.

Agencies who are about to renew their maintenance vehicle fleet, could use this opportunity to calibrate their new fleet to be used as data collection probes.

Additional products and activities (e.g., summaries, presentations, training workshops, peer exchanges) will help create awareness and facilitate implementation of the research results.
